SPECIFICATION forming part of Letters Patent No. r7 2?',09O, dated May 5,1903.

To ctZZ whom, t may concern:

Be it known that I, IRvING G. CHATFIELD, a citizen of the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvementsin Detachable Fire-Boxes for Cook-Stoves, of which the following is a specification. v

Myinvention relates to new and useful improvements in detachable fire-boxes for cookstoves, the same being particularly adapted for burning charcoal, soft coal, and the like.

It is the object of the invention to construct an inexpensive sub fire-box which has a contracted lower portion to fit in the regular rebox of an ordinary cook stove or range by simply removing the two front lids and crossbar therefrom and seating the boxin the opening therefor. Further, to so arrange the fireboxthat the covers removed from the stove can be utilized for covering the box, thus having the stove present substantially its original appearance. Finally, to provide openings in one side of the pot and a shield or guard for the fire-box adjacent to said opening to insure the draft for the stove passing through the fire-box and its fire as desired.

With the above objects in view my invention resides and consists in the novel construction and combination of parts shown upon the accompanying drawings, forming a part of this specification, upon which similar letters of reference denote like or corresponding parts throughout the several figures, and of which- Figure l shows a plan View of myfimproved fire-box complete. Fig. 2 is a side elevation, partly broken away, illustrating the box partially in a central vertical longitudinal section. Fig. 3 is a transverse cross-section taken in line 3 3 of Fig. 2, the same more clearly illustrating the offsets or shoulder formed on the lire-box, together with the shield for controlling the draft.

As will be apparent from the illustration, my fire-box consists practically of two pieces,

' one being a casting, which is light and can Serial No. 132,552. (No model.)

formed of sheet metal secured to the rear 0f the box.

Referring in detail to the characters of reference marked'up'on the drawings, A represents the fire-box as a whole, and B the shield.

c indicates the top rimlof the fire-box, and d the end extensions thereof, having liftingholes e formed therein.

f represents an external shoulder which in Apractice rests on the edge of the hole in the top ofthe stove. The body of the Yfire-box below this shoulder is of a size corresponding to that of the opening formed for the covers, which obviously insures the fire-box resting snugly within the lire-box of the stove and central thereof. A series of transverse openings h are formed in the bottom of the rebox,'thus producing grate-bars c', upon'whi'ch the'bed of the fire rests in the usual way, thel ashes from which can be Worked down with a poker, brush, or small broom, as is the custom with a charcoal lire.

O n the rear side of the grate I form a series of openings j, through which the products of combustion pass out into the top of the stove and thence'off through'V the smoke-passage of the same in the customary way. Upon the same side of the grate and adjacent to these openings is located an external shield B. The bottom k of this shield in practice rests upon the top of the oven portion of the stove, and the ends Z of theshield close the space between the end'of the' grate and the sides of the stove intermediate of the ends of the grate and the space formed over the top of the oven, thus avoiding any draft around the box, but insuring such draft passing through the box and out of the openings j referred to.

On the inner edge of the top rim c of the grateI form anA annular recess m to receive the three front covers indicated in dotted linesv in Fig. 1, which, as before intimated, would be the same covers that were taken from the stove for the reception of the grate, thus making it possible to use the stove in the same way with this grate and a charcoal fire as would be with the ordinary grate andcoal re.

From the foregoing it will be seen that I arrange the lire-box so as to form a compartment which will not be so deep as that ordinarily found in cook-stoves, thus providing a Ico shallow fire nearer the surface than it Would be if the fire were built in the ordinary deep fire-box of stoves of this class. It is further true that owing to the peculiar nature of charcoal a tire can be used in one end of the grate only more economically than a coal re could be used in the ordinary coal-grate. This could be used With or Without a transverse partition. Should the latter be desirable, it could be formed of any suitable piece of metal and inserted through one of the transverse openings between the grate-bars, as indicated by n in Fig. 2.

Having thus described my invention, What claim, and desire to secure by Letters Patent, is-

l. Adetachable Iire-boX for cooking-stoves, the same comprising a top formed of a single piece having a grated bottom and of a shape andsize to fit into the stove-opening, and having openings in the rear side of the pot, a shield secured to Said side, the same adapted famoso to form an inclosed passage from the box to the top ue ofthe stove, thus insuring a draft through said fire-box, Substantially as described.

2. A fire-box comprising a body having an annular rim, a recess formed on the inner edge of said rim to receive the stove-covers, a contracted lower portion to said fire-box with transverse grate-bars forming the bottom proper and openings through the side of the fire-box, a shield comprising a bottom and end port-ion to constitute a ue for said fireboX and to deflect the products of combustion into the flue-channel of the stove, substantially as described.

Signed at Bridgeport, in the county of Fairfield and State ot' Connecticut, this 30th day of October, A. D. 1902.
